complex vectors and matrices
(30 minutes to learn)
We can define complex vectors and matrices with properties closely analogous to their real-valued analogues. Complex matrices come up when dealing with eigendecompositions of non-symmetric matrices. They are also used in computing the fast Fourier transform.
This concept has the prerequisites:
- Know the definitions of the Hermitian operator and the complex dot product
- Why is the Hermitian operator used for complex matrices rather than the matrix transpose?
